Specification of Letters Patent.

Application filed July 22 1907. Serial No. 384,855.

To all 'whom it mi2/g" concern.' l

Be it known that l., -HENRY D. GruIswoLn,

. Providence and State of Rhode lsland, have invented certainfnew and useful improvements in Bicycle Handle-Bars, of which the reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in adjustable extension for bicycles and has for its ob.- i to provide by thel handle bar may be permittel to project forward of the head, and also raised to and be substantially universally adjusted in said member'.

A further object is to make thedevice so that it may be readily adjusted, quickly set and firmly fastened in any desired position. rllie device is very simple of construction and inexpensive to manufacture, the same being vlight in weight and at the same time very and. d arable.

' An essential `feature of this invention is to' so construct the device that it may be supported in the fork tube by an expanding strong, still ead.

Still another feature of the invention is by said sleeve is retained in position on the extension member, and also caused to bind and hold the handle bars in any desired positidn all by the setting up of but one binding mit which is located on the end of said 'extensign member.

he .invention fully set forth in this specification and more particularly pointed out inv the appended claims. t

ln the accompanying drawings: Figure l-is a side elevation showing a portion of the fork head and the extension member supportedon said head, in its forwardly extend-l ing position and the binding sleeve turned downward on the end thereof retaining the handles in their downwardly Xtendmg position. Fig. Q--is the same as Fig. 1 with the bil exception that the binding sleeve turned up and the handle barsare 1n their reverse or upwardly turned pos1.t1on. Fig. 3-1s an enlarged sectionalview illustrating' the construction and operationof th e parts'. Fig ll---is a plan view on line 4-4 of Fig.. 3, showing the'binding bolt .for the extension member. Fig. -1s a side elevation of the binding .sleeve showing kthe corrugated face which engages a corres an extension member wheresleeve wherel ending facefon the binding member for rmly' retaining said sleeve in the desired position.

Referring to the drawings at 1 is the head of the bicycle frame in whichV the fork tube 2 is held to turn. Into this fork tube tsithe binding post member 3- the lower end of the tubular portion being slotted .at/4e to of expansion. This lower end is alsoibeveled slightly to receive a correspondingl shaped plug 6. The upper end of this bind?I ing head is provided with anf'ear 7 ofset or placed on one side thereof so as to-allOW forA the binding bolt 8 to pass through the upper, solid portionof the head. entends`- down andis threaded at 9` into: the beveled eXpansion plug 6'. The'face of this ear 7 is provided with radial teeth 1 ().Whch

project across its -face around the outwardlyr extending. retaining bolt 11'(see'Fi .4).

At 12 isv an extension arm provide with an offset ear 13 pierced at 14 to t over the binding bolt 11. The face of this ear at 15 isprovided vwith radial co'rrugations to. reglster with those on the binding-post member. At the outer end of this extension arm is an outwardly extending bolt Q4.- threaded at at its outer end. The

face from which this bolt extends is also` ro.-l

vided with radial teeth 26. The. bining sleeve 16 is adapted to't over the handle bars 21 andis provided with twov outwardly face 10 of the ear on thev admit` A 7.0. This binding bolt extending ears 1 7-17 which ears are split at 1S so as to admit of the sleeve being set together to bind and hold the bars'in the desired position therein. `Both lof theseears are pierced at 19 to lit over. the outwardly eirtending bolt 24 and the face of orient-these" earsis provided with radial teeth 2 0,A which register with those onthe face 26 of the extension arm. y

` The operation of my invention may be4 more fully described as' follows: In assem- 'bhng the parts of the steering head, the bind- 'ing` post member 3v is placed in the fork 2 by setting up on the binding bolt 8,'the lower end of this tubular post is eXpsmd-ed` and rigidly secured in the fork-member; construction of `my extension 12 thev same may be set in any desired positionfrom straightuip, as shown i the By the,

dotted lines lin' Fig. 3, to `pointing on an angle dow'rvivard,y

as Yshown in the dotted lines in Fig 2, and by settin up the nut 22 to cause the radial teethl di of the contacting faces toengage' ea h on bot other said arm is held firmly in thedeslred .combination .head which is only accomplished by the oli'setofthe handle bars moving 16 in which the bar'lits closely.; Theears of' this sleeve -are'passed overthe bolt'24and b simply turning this sleeve around on this be t the handlev bars may receive a downward curve as shown in- Fig. 1,- or by simply turn# ing the sleeve upward the handle bars re,-v celve the reverse curve extending upward, as shown in Fig. 2.

Byjiny improved construction the adustvme'ntof these bars into any-..desired'pos1tion` i'san ,extremely simple operation there being but two nuts to o erate to secure the widest adjustmentof sai bars. V

"An essential,A practical feature of the construction is the arrangement of the binding sleeve" whereby the two `ears of. this sleeve vextend over. the'bolt 24, one faceofv one ear being corrugated to engage a corresponding face on the extension arm whereb said bars may be very readily adjusted andy may be firmly locked in 'anly bythe simple 'operationo but one indi'ng nut.

Anotherparticularly good feature from a practical standpoint is the arrangement whereby anextension arm -may be used in with yan expanding Abinding tlngfo'f the ears in' which said extension .arm

is p voted so thatthe expansion bolt .8 may' 'be yoperated through the top of the post. v.

` The vdevice'isjvery practical in construcswhole is-very rigid and there is no possi ility or becoming loose, which-is a `most essential featurey where fast riding is-desired. A

the Whole desired osition the I vHaving h us 'describedy my invention, what I c laimas new and desire Ito 'secure'fby ters'Patent, is: l 1. A'n' improved .handle bar, com rising ali-514 expandible binding post provide withen integral offset ear, .an extension member pori `videda`toneend with an integral offset ea ,o means for pivotally. .connecting said ely/r# whereby said extension pie'ce'is rendered/ ray 5| dially adjustable, means for-securing said'e'xf tension member in any .positionwithin lits rangefof adjustment, and a binding sleeve .carried by the free end'o'f said extension and ladapted to receive a handle bar.. 5g
